Question 42 • 25-26 TX-Physics A-CR

What is an advantage of genetically engineered biological pacemakers developed by biomedical engineers over electronic pacemakers?

Answer

Biological pacemakers have been used much longer than electronic pacemakers.

Biological pacemakers inject cells into the patient rather than use surgery to insert an electronic pacemaker.

Biological pacemakers can be removed when they are no longer needed, but electronic pacemakers can never be removed.

Biological pacemakers work on all patients, but electronic pacemakers only help those patients who have had heart attacks.

Explanation

A biological pacemaker is made by introducing genetically engineered cells into the heart so they can help regulate its rhythm. This may avoid implanting an electronic device through surgery, as choice B describes. Choice A is incorrect because biological pacemakers are a newer development, and C and D make inaccurate claims about removing electronic pacemakers and who can benefit from them.
